The IRNA report on Sunday said Gholamreza Khosravi was sentenced to death in 2010 for providing photos of the country's military facilities and financial aid to the MEK, and for helping to recruit for the group.

It said Khosravi was arrested in 1997, after having been previously detained from 1981 to 1986.

The MEK began fighting to overthrow the Islamic Republic shortly after the 1979 revolution that toppled a pro-Western monarchy.

The MEK was based in Iraq during the reign of Saddam Hussein, who waged an eight-year war against Iran in the 1980s.
